'p The .improved sheet handling mechanismz to which this invention isapplied is adaptf cdfor use in many c'liferent types offma.- chines andfoi" handling various kinds of articles but, as herein illustrated, theinven tion is applied to a stencil making machine.v

Inasmuch as this invention relates tothe sheet handling mechanism, partsofthe machine not relating thereto and believed to he unnecessary to acomplete understanding of the invention have beenl omitted from thelline ft2-l2 ofl Fig. l, and showing theimconveyor which Ainoves thecards' or other'. Y

sheets seriatimto be operated uponhy the various operating mechanisms.The particular conveyer herein illustrated comprises l anendless chainhaving projecting parts adapted to engage apertures in the articles,

which, are ted thereby 'y along a supporting guideivay. Tliesheets orcards are. dgliyv ered to the feeding mechanismby an improved deliverymechanisin which, in the specific form shown,V includes a magazine' andmeans/for moving the lowermostcard i to the plane of the guidevvay forengage- `ment With the lugs or fingers of the con` veyer. An improvedejector is also pr0-' vided for removing the cards `when they reach acertain position on the guideway.

In order to properly position eachf card" when it being acted upon,improved po sitioning means is `also provided fortenn porarily holdingthe card stationary.` y rp vIn the embodiment shovvmpthelimproved sheethandling mechanism 'y applied to a stencil inakinginachine comprising aframe.,

l on which is mounted a pair'of spaced rails 2 forming a guideivay forsupporting and guiding stencil frames 3 Whichare fed through the machineto be operated upon by various mechanisms such as a. gluing` devicelland a pneumatic device fwhichappliesthe tissue patches to the stencilframes;

" gear 17 fixed on a shaft 18.

" sition to be acted upon by the gluing device 4 and the pneumaticdevice 5. Arranged at the other end of the machine, is an improvedejector 9. l

In the specific form shown, the chain conveyer 6 vis mounted on a pairof sprockets 10 and 11, which are fixed on horizontal shafts 12 and 13respectively journaled at opposite ends of the machine. The sprocketshaft 12 is journaled ina bearing 14 which is adjustably mounted on asupport 15, so as to be adapted for adjustment both vertically andhorizontally for properly positioning the chain. Fixed on the outer endof the shaft 12, is a worm gear 16 meshing withY another The shaft 18 isconnected to a continuously driven drive shaft 19 by a Geneva mechanism20 so as to be intermittently rotated for imparting a step-by-stepmovement to the conveyer chain. The sprockets and 11 are arranged so asto position the upper ruiming part of the conveyer chain adjacent oneside of and parallel to the card guideway 2. Mounted on the chain 6, isa plurality offingers or lugs 21 which project over the adjacent guiderail for engagement `with apertures 22 formed in the card frames,whereby the cards or stencils are fed along the guideway. The lugs 21and apertures 22 are positioned so as to prevent any lateral shifting ofthe stencils during their travel along the guideway.

In theform shown, the improved delivery mechanism 7 comprises a magazineor hopper 23 in which a stack of cards or stencils is stored and fromwhich the lowermost card is pushed edgewise by a pusher 24 arranged tomove the card onto a pair of cams 25 which lift it into the plane of theguideway 2 for engagement with the fingers 21 of the conveyer.

The pusher slide 24 is located `in a guide-- way 26 below the magazine23 and is reciprocated by a rocker arm 27 to which it is pivotallyconnected. The rocker arm 27 is pivotally connected at 28 to the frame 1and is pivoted at its lower end topaJ link 29 having a band 30 embracingan eccentric 31 fixed on the drivel shaft 19. During the continu.ousrotation of the shaft 19 and eccentric 31, the arm 27 is rocked backand forth to reciprocate the slide 24 which, upon each forward movement,pushes the lowermost card in the magazine onto the' cams 25.

The lifting cams 25 are mounted on shafts 32 arranged below andparallelto the guide rails 2. Fixed on the shafts 32, are pinions 33meshing with a gear 34 of a train of gears driven by the drive shaft 19,whereby the cams 25 are continuously rotated. The rotation of the cams25 is synchronized with the movements of the pusher slide 24 andconveyer chain 6 so that when the pusher moves forwardly, the flatportions of the cams 25 are rsubstantially parallel to the plane of theguideway 2 so as topermit the card or stencil to ride upon the cams, lnorder to secure the cards against dropping between the cams 25, a pairof brackets 35 is arranged in position to support the ends of the cardadjacent its middle portion. The cams 25 rota-te in the direction of thearrows, Fig. 4, and lift the card into the plane of the guideway 2 so asto permit the depending conveyer lingers 21 to engage the apertures 22.

In the form shown, the improved positioning device 8 includes acontinuously ro-4 tatable horizontal shaft 36 journaled in the frame 1and extending substantially parallel to the guide rails 2 directly abovethe path of the stencils. The shaft 36 is connected to the drive 19 bythe train of gears shown at the right end of Fig. 1. Mounted onl theshaft 36, is a series of semi-circular flanges 37 spaced apart adistance slightly greater than the length of the card or stencil beingoperated upon. The flanges 37 form stops for engaging the forward' edgesof the cards to accurately position them at certain stages in theirtravel. One of the stops holds the card in position for engaging thechain conveyer and the other stops position the cards for properengagement with the gluing device 4 and pneumatic device 5. Also mountedon the shaft 36, are semicircular cams 38 adapted to engage the rearedges of the cards for urging them forwardly against the stops 37.- Toprevent injury to the cards or stencils, the cams 38 are cushioned byhelical springs 39 embracing the shaftj'36, as clearly shown in Fig. 6.The cams 38 are keyed to the shaft 36 so as to permit the yieldingaction of the cams. The end card, which is being acted upon by thelift-ing cams 25, .is urged forwardly into engagement with the adjacentstop 37 by an upright blade 40 pivotally mounted in 'the frame 1. Theblade 40 is normally urged forwardly by a spring 41 and is arranged tobe acted upon by the end of one of the cams 25 for retracting it intoposition for engaging the next card. f

The improved ejector 9 comprises a pair of cams 42 fixed on a shaft 43journaled in a bracket 44 which is mounted on the frame 1. Fixed on theshaft 43, is a worm gear 45 meshing with another worm gear 46 on a shaft47 which is geared to the drive shaft 19, whereby the ca1ns42 arecontinuously rotated in the direction of the arrows, Fig. 12.

The cams 42 are spaced apart a distance lslightlylcss than the lengtlrola stencil 'so as to engage the end portions of the :stencil frame 3,thereby avoiding injury to the tissuev patch. In order to permittheendcard toadrop from the guideway when pressed downwardly by the cams42, the outerguide rail k2 .is provided with a. yieldingportion 48 whichsupports the outer edge of the end card and which is adapted to swingdownwardly to releasethe card under vthe pressure of the cams 42. t Theyielding portion 48 is in.` the form of a stirrup, pivote-d to thebracket 44iby a pin 49. The stirrup 4S is nonmallywheld in `positionforsupporting the car'd byV means of a spring 50 embracing the pin 49. Asuitable receiving hopper or conveyor, not shown, may be placed belowthe cams 42`or1eceiving the ejected cards.

I In operation, the chain conveyer G travels in` a step-by-step:movement through :the action ot `the intermittently rotating `shaft 18.During each brief period of rest ofthe chain-.6,1m card is ted from themagazine 23 bythe pusherslide 24y which moves it onto the `lifting cams25,. 4The cams 25 are continuously' rotated and lift the cardV intotheplane. of ythe guideway 2 for engagement with a pairof lugs 2l on thechain 6. The chain (Sgt-hen moves another step to carry the card ,intothe guideway 2. The cards are fed along the guideway tobe operated uponby the various mechanisms and, when eaclr card reaches` the ejectormechanism, itis forced out of the guidewayby the cams 42. Vith thisimproved sheet handling mechanism, the articles are fed positively fromone station to the next without` any possibili ity ofV amming. iT heapertures 22 serve for handling the stencil frames in the Variousoperations ot making stencils and also for handling in the machines inwhich the stencils are used. y i
